选铜尾矿水力分级分选提纯试验研究OACHSSCD

Copper tailings still retain some copper minerals,and graded sorting can improve resource utilization and reduce environmental risks.The experiment uses a hydrocyclone and a fluidized bed separator to recover and enrich copper minerals from copper tailings.The experimental results show that both devices can effectively enrich copper minerals in copper tailings,and the classification effect of hydrocyclone is better,while fluidized bed separators can achieve lower bottom abortion rate,lower overflow copper grade,and higher bottom flow copper grade,resulting in better separation effect on copper minerals.
